Catalog HIC

Danfoss offers various pre-engineered HICs, including fan drive, motor mount, spreader, and traction control solutions. These systems accommodate a wide range of flow and pressure ranges to match specific motor capabilities.

Fan drive features and benefits 

  • Six pre-engineered hydraulic integrated circuits (HICs) available to provide speed control and reversing for hydraulic modulating fan drive motors in open-circuit hydraulic fan drive systems.  
  • Various frame sizes and options available
  • Variable piston pump or fixed pump circuits  
  • Over-pressure protection and anti-cavitation   
  • Viton O-rings 
  • Proportional fan speed control enables electronic matching of fan speed with cooling demand 
  • Reversing function enables purging (declogging) of coolers and radiators 

Motor mount features and benefits 

  • Direct mount to motor provides optimum control at load  
  • Pre-work enables proper assembly and mounting to motor 
  • Mounting bolts and O-rings included 
  • Pre-testing to NFPA test standards enables robustness on your application 
  • Designed to match technical capabilities of motor 
  • Available designs include counterbalance, cross-port relief, bypass solenoid, and shock valve with anti-cavitation protection 

Traction control features and benefits  

  • Efficient drive solutions on vehicles where one pump drives multiple motors 
  • Solutions available for two- and four-motor systems to deliver equal flow to motors once actuated, preventing wheel spin and excessive motor speed 
  • Custom bypass valve provides extremely low pressure drop with traction control dis-engaged, improving system efficiencies and reducing heat 
  • LFB12 flushing block  assists in removing contamination and cooling oil, helping sustain high-quality working fluid in a hydraulic transmission circuit 

Spreader features and benefits 

  • Load-independent flow control for two functions 
  • Commonly used for ice and snow control on sand/salt spreader vehicles 
  • Detented hand knob with minimum and maximum stops and 11 positive positions provide easy adjustment 
  • Dual control of two actuators, typically auger and spinner 
  • Pressure compensation for load-independent flow/speed control of motors 
  • Manual or electrical control for unloading 
  • Load sensing capability for open-circuit piston pump circuits (SPR-2FFLC12) 

Applications 

  • Agriculture 
  • Construction
  • Cranes and material handling 
  • Forestry 
  • Lawn and turf care 
  • Road building
